Manuscript Summary: This French translation of the story of Alexander, destined to belong to Charles the Bold, was commissioned by Vasco da Lucena, "the Portugese", a retainer of the Infanta Isabella, who was married to Philip the Good. This revival of the work by Quintus Curtius Rufus, which is augmented by texts from Plutarch, Valerius Maximus, Aulus Gellius and Justin, allows the author to liberate the Macedonian conqueror from legends perpetuated by the medieval tradition. The Miroir des princes portrays a model of a hero shaped within the framework of the humanistic movement initiated by the dukes of Burgundy in the late middle ages. CB 53 was copied in Burgundy and may be fairly accurately dated only a few years after the translation was made; it was decorated with miniatures in the artistic circle of the Master of Marguerite of York (ca. 1470-1475).
